1.
Excavate an area large enough for the Fusion
unit. Excavation dimensions are calculated by adding 12-18" (305-457 mm) to the length and width of the Fusion
sufficient room for proper backfilling.
2.
Construct a 6" (152 mm) thick stone pad of either 1/4" - 1/2" (6-13 mm) diameter stone or concrete pad and level to within 1/8" (3 mm).
3.
If the unit is not level, it will cause uneven water flow as well as unbalanced aeration, which will result in poor
performance.
4.
Gently lift the unit at all four lifting points with a harness and install it on leveled stone pad (Figure 9).
5.
Check unit to make certain it is level by placing a level at several locations on the riser. (riser covers removed) (Figure 9).
BACKFILLING
1.
If groundwater is present, anti-flotation measures must be
used to stabilize the unit prior to backfilling. Please follow the
procedures in the Anti-flotation section to properly anchor
the Fusion
®
.
2.
Fill the unit with clean water to the normal operating depth
prior to backfilling. Partition walls between chambers are
water-tight and will fill in succession beginning on the inlet side
of the unit. Therefore, it is best to alternate chambers when
filling with water so the unit remains level. Check for leakage
around the unit.
3.
If necessary, install riser extensions on the adapter rings
prior to backfilling. See Table 1 for number and size of access
openings. Riser extensions are available for deeper burial.
Make certain risers are sealed properly and watertight.
4.
CAUTION
Apply two beads of silicone fully around each
riser section prior to securing with supplied screws.
5.
Install riser covers.
6.
Backfill with good quality granular soil around the unit that is
free of organic matter, rock, stone, tree roots, or other debris
that could damage the unit.
7.
Tamp soil around perimeter of the unit as it is backfilled to
stabilize the unit and to reduce settling.
8.
Finalize backfill with a mounded contour so that surface water
is shed away from the unit. Under no circumstances should
surface water be allowed to accumulate around unit.
9.
CAUTION
MAXIMUM soil burial depth over the unit is 36
inches (914 mm).

COLD WEATHER INSTALLATION
When installing Fusion
specify insulated lids and risers. In addition, the blower must be
protected from snow drifts. If installed in a riser, the blower must
be protected from inundation and may have a vent pipe installed
to above the maximum snow depth with a 180 degree angle at the
end to prevent snow and water entry. Also, the top and sides of the
Fusion
may be insulated with insulation sheeting or other means
®
to provide a minimum insulation value of R-8. Please contact the
factory for further information.
ANTI-FLOTATION PROCEDURES
It is necessary to anchor the Fusion
conditions to prevent flotation. If groundwater rises above the rock
or concrete pad that the Fusion
Please consult a design engineer, soil scientist or other qualified
individual to determine high groundwater conditions.
1.
Follow the procedures outlined in the Excavation and
Installation Section, items 1-5, to properly prepare and level
the Fusion excavation.
2.
Follow the procedures outlined in the Backfilling Section,
items 1-4 to properly fill the Fusion
if needed.
3.
Refer to Figure 10, Anchoring Schematic to determine the
minimum amount of backfill to be placed around the Fusion
in the excavation. Tamp the fill to prevent settling.
4.
Refer to Table 3, Concrete Anchoring Dimensions, to determine
the amount of concrete needed for the concrete anchor collar
that is poured around the entire circumference of the Fusion
Pour concrete to the specified dimensions to fully engage

concrete cures. Make certain to pour the concrete in a manner
to minimize trapped air within the concrete. Agitating or lightly
mixing the concrete with a metal rod or other similar device
once poured will help release trapped air.
5.
Allow the concrete to harden before final backfilling.
6.
Complete the procedures outlined in the Backfilling Section,
items 5-8.
